It's been a while since my last update.. let me bring you up to speed.

A couple of libffi releases got in the way of moxie hacking
(although libffi 3.0.13 now includes full moxie support!), but things
are picking up speed again.

On the software side of things, the moxie RTEMS and QEMU ports
have both been accepted upstream. So now it's possible to build, run and
debug RTEMS applications on QEMU purely with upstream project sources.
You may notice that I'm doing much less work in the moxiedev
repository these days. This was mostly just a staging area for moxie
software support (tools, OS), and there's little use for it now that
most everything is upstream. All of the moxie HDL work now happens in
the moxie-cores git tree.

As for the hardware side of things, here are some of the recent changes:

A simple interrupt controller has been added to the marin SoC. I
have the Nexys3 momentary switches hooked up as interrupt sources,
so I can trigger interrupts and handle them in software by pressing
those buttons.

A trivial timer has been hooked up to the interrupt controller, so I
can now generate 'tick' interrupts for RTEMS in support of
preemptive multitasking (everything was cooperative up 'til now).

I'm actually just debugging the timer ticks right now, but it's very
close.
